  • Install neat up to 1” (25.4 mm) and up to 3” (7.6 cm) with aggregate

  • A blend of Portland cement and other hydraulic cements

  • Provides a smooth surface prior to floor covering installation

  • Fluid consistency for ease of application

  • Rapid setting

  • Mixes with water only - no latex additive necessary

  • No primer required over concrete

  • Exceptional bond strength

  • Ideal for ramping, patching large areas and screeding. It is a self-drying, fast setting, trowelable patch for smoothing and repairing concrete floors, ramps and stairways, as well as non-porous substrates such as terrazzo, ceramic and quarry tile, prior to the installation of common floor coverings (60 minutes). Over non-porous substrates, the use of ARDEX P 82™ Ultra Prime ensures a permanent repair

  • Cure 16 hours for wood, adhesives, epoxies and urethanes

  • Recommended Tools: ARDEX T-2 Ring Mixing Paddle, mixing bucket, margin trowel, wood or magnesium float, steel trowel and a 1/2” (12 mm) heavy-duty drill (min. 650 rpm)

  • For one 40 lb. (18 kg) bag of ARDEX SD-P RAPID, use 4 quarts (3.8 L) of clean water. Pour the water in the mixing container first, and then add the ARDEX SD-P RAPID. For best results, mix with ARDEX SD-P® RAPID Self-Drying, Trowelable Concrete Underlayment an ARDEX T-2 Ring Mixing Paddle and a 1/2” (12 mm) heavy-duty drill (min. 650 rpm). Mechanical mixing will produce a creamier, smoother consistency without the need for additional water. DO NOT OVERWATER! Additional water will weaken the compound and lower its strength. To mix smaller quantities by hand, use 3.5 parts of powder to 1 part of water by volume. Use a margin trowel and mix vigorously for 2 - 3 minutes. Just prior to application on the substrate, the mixture should be stirred again to ensure a creamy, smooth, lump-free consistency. The pot life of ARDEX SD-P RAPID is approximately 30 minutes at 70°F (21°C). If stiffening or surface skinning occurs within this time, remix before using. After mixing, apply the ARDEX SD-P RAPID to the substrate with a wood or magnesium float to obtain a solid mechanical bond. Allow the material to take a set (approx. 30 minutes), then finish the surface using a steel trowel. Note: Attempting to finish the surface with a steel trowel before the material has taken a firm set will result in blistering
